Sindee found out recently that the copy of Microsoft Office installed on her computer was a pirated copy. She purchased a new copy, removed the pirated program, installed the newly purchased software, but discovered that the product key from the pirated version remains on her computer. She is now unable to download any updates to the program and wonders how to fix the situation.
Product keys for Microsoft Office are stored in the Windows Registry. If you want to install a copy of Office that uses a different product key, then you need to delete the place in the Registry where the product key is stored. You do that by following these general steps:

When you start an Office application, you will then have the opportunity to enter the new product key. If you prefer, you can uninstall Microsoft Office before you do the Registry editing, and then reinstall the software from scratch.
If you don't feel comfortable editing the Windows Registry or if you run into other problems doing the uninstall, you can try a free utility such as Revo Uninstaller:
The program is much more thorough in its cleaning capabilities than is the regular Windows Uninstaller. It can get rid of all vestiges of Microsoft Office, and then you can reinstall the software with no problems.
